' Specification of Letters Patent.

Be it known that, we, Gtrs'rAr H. SGHEF- STROM and Omar A. ANDERSON,citizens of the United States, and residents of .Macomb in the county ofMcDonough' and State 0 Illinois, have invented certain new and use fulImprovements in Ice-Creepers, of which the followingis a specification.

The present invention relates to new and useful improvements in icecreepers and the 4 like and has for its primary object the provision ofan improved type of ice creeper capable of application to various typesof shoes regardless of size, shape or material.

Many ice creepers now in use are incapable of application in connectionwith rubber boots'and other footwear and it is I therefore one of theprincipal'objects of our invention together with the foregoing toprovide an ice creeper which may be applied in position on a rubber bootas well as on the regular leather shoes.

Another object of our invention is to provide an ice creeper of theclass described which is adjustable both in length and width to varioussizes of shoes, the ice creeper being so constructed as to automaticallyconform to the shape of the sole of the shoe or boot when a pliedthereto.

Other objects and advantages to be derived from the use of our lmprovedice creeper will appear from the'following detail description and theclaims, taken with an inspection of the accompanying drawings, in which:

' Figure 1 is a top plan view of an ice creeper embodying theimprovements of our invention;

Fig. 2 1s a longitudinal sectional view taken on the line 2-2 of Fig. 1;and.

Fig. 3 is an enlarged fra ental perspective view of the connection.etween the heel and sole sections of our improved ice creeper.

Referring more particularly to the drawings, wherein similar charactersof reference designate like and corresponding parts throughout thevarious views, land 2 designate in their entireties the heel and solesections of our improved ice creepen, ferring specifically to the heelsection the frame is preferably formed of a sheet of 'metal having thecentral portion thereof provided with an opening 3 for lightening same,suitable calks 4. being arranged to project from the underface thereof.The

rear free end of the plate 1 is tapered as at' '9 and 10,0r the like.

The sole section of our improved creeper comprlses preferably a pairofarms 11 and 12 hingedly connected by a rivet 13, said rivet having anelongated head 14 for a The free end portions of the arms 11 and 12 areprovided with upstanding tongues 15 arranged at an angle relative to thelongitudinal axis of said arms and having connected thereto, by means ofrivets 16 or the like, fastening means, such as straps 17.

The arms 11 and 12 intermediate their ends are connected by means of apair of links 18, said links being pivotally connected as at 19 andconnected with said arms 11 and 12 as at 20. The'connecting members 19and 20 preferably form calks and have projecting heads 21.

Theheel and sole sections are adjustably connected by means of a link 21riveted at 22 to said heel section 1 and being provided adjacent thefree end thereof with a plurality of transversely arranged elongatedapertures 23. As best shown in Fig. 3 the elongated head 14 of the rivet13 is rigidly carried by the arms 11 and 12 in such a way that said headnormally lies approximately coincidental with the longitudinal axis ofthe creeper. To connect the heel and sole sections the sections areplaced relatively at right angles and the head 14 is inserted throughone of the apertures 23. When the ice creeper is straightened forapplication to a boot or shoe the head 14 becomes arranged atrightangles to the opening into which thesame has been insertedpreventing-its dislodgment therefrom. The sole section willautomatically adjust itself in the shape and size of the wea'rers shoeor boot when the fastening straps 17 are applied in position.

From the above description taken 1n connection with the accompanyingdrawing, it is thought that a clear and comprehensive understanding ofthe construction, operation and advantages of our invention may be had,and while we have shown and described our invention as embodying aspecific structure, we desire that it be under.-

purpose which will hereinafter appear.

stood that we may make such changes in said structure as do not departfrom the spirit and scope of the invention as claimed.

Having thus fully described our invention, what we claim as new anddesire to (secure by Letters Patent, is:

1. An ice creeper of the class described, including heel and solesections, connecting means for said heel and sole. sections comprising alink having elongated openings therein, said sole section being com osedof a pair of arms pivotally connecte at one of their ends to the saidconnectm means,

. pair of'links, and a plurality of ca k members, one of said calkmembers pivotally connectin the links "at one of their ends, theopposite ends being pivotally connected ing one end thereof pivotallyconnected to the said heel section, the opposite end of the link beingprovided with a plurality of transverse elongated openings, a rivet, apair of arms pivotally connected adjacent one of their ends by means ofthe-said rivet, said rivet having an enlarged head adapted to engage inthe said openings, the free ends of the arms being provided withupstanding ton es, fastening straps attached to the sai tongues, aplurality of calks, and a pair of links pivotally connected adjacent oneof their ends by one of the said calks, the opposite ends thereof beingpivotally connected to the arms intermediate the ends thereof by meansof calk members, the said links providing alsupporting means for the toeof the shoe.

In testimony tures hereto.
